Comparing hostip and geoip

What is the best IP address to geolocalisation system?

Seeking to analyze web log files by the country of request origin, I recently proposed a simple plugin wrapping hostip.info API. Of course, the major competitor in the field is maxmind geoip and they provide a free light version of their database. This database can be queried through their java API of a geoip Grails plugin.

Time has come for numbers. How each module perform on the same set of ip address? Even with 3% of uncertainties, maxmind geoip lite shows to be clearly the best.

hostip grails plugin: from IP address to localisation

Getting a localisation from an IP address is somehow straight forwards with available web services. However, for massive report (such as analyzing web logs from the remoteIP perspective), it is not doable, even with caching.
The idea of the plugin is to use the free distributed hostip database, mirror it locally and give a Grails service to query it.
